Why so Blue?

A few people have noticed that photos in the Kootenays are really very blue.

“Is something wrong with your camera, Abby?”

Well, no. This is atmospheric perspective at work – the effect of the atmosphere on viewing distant objects. The further away a mountain is, the more blue light from the sky is scattered across the line of sight, and the more blue the distant mountain appears.

And as the Kootenays are layered with distant mountains and moist air, everything turns pretty blue on a sunny day!
